We investigate the dynamic evolution and self-healing properties of the bored helico-conical
beams with different filter parameter S in this paper. The relative error coefficient, D, is …

In this paper we revisit the nondiffracting properties of the cosine beam (CB). Since the CB is
of infinite extension and not physically realizable, we use two apodization pupils to manage …

Abstract High‐order Hermite–Gaussian (HG) lasers oscillating at multiple wavelengths are
extensively needed for generating vortex lasers carrying orbital angular momentum (OAM) …

To the best of our knowledge, at the present time there is no answer to the fundamental
question stated in the title that provides a complete and satisfactory physical description of …

The connections between Laguerre–Gauss and Bessel–Gauss beams, and between
Hermite–Gauss and cosine-Gauss beams are investigated. We review different asymptotic …

Here, we present an experimental method that redistributes the optical energy among the
lobes of high-order standard Hermite–Gaussian (SHG) laser modes in a controlled manner …

Binary optical gratings are used in applications such as optical metrology. Due to the fact,
that self-imaging phenomenon depends on the grating fill factor, in present work the effect of …

The multiple lobes of high order Hermite-Gaussian (HG) laser modes differ in terms of
shape, size, and optical energy distribution. Here, we introduce a generic numerical method …

It has been known for some time that Bessel–Gaussian beams and their associated families
self-heal after encountering obstacles. Recently, it has been shown theoretically and …

We introduce the generalized fractional Hermite-Gaussian (GFHG) beams, a type of
structured light based on the fractionalization of Hermite functions. By incorporating a …
